"Sisu. From none other than Wikipedia, Sisu “is a Finnish term loosely translated into English as strength of will, determination, perseverance, and acting rationally in the face of adversity.” If you take the literal translation, it is equivalent in English to “having guts”.

While maybe not yet a master of sisu, the Finnish blueliner prospect definitely has some degree of sisu now; an excellent foundation upon which to build as he grows as a player and a person.
With a big blow to the blueline when Olli Määttä was injured in Finland’s first game of the WJC U20s in Calgary, Pokka’s role increased substantially. The young defenseman did not disappoint exhibiting his solid 2-way play which leans towards the offensive side. Pokka finished the championships tied for 6th in scoring amongst defenseman scoring with 4 points in 7 games."
